• Vitamin C (15% THD) — an ultra-stable, fat-soluble, highly potent form of Vitamin C in an optimal concentration. Visibly improves skin appearance without irritation, even for sensitive skin.
• Niacinamide 3% — works synergistically with Vitamin C to inhibit tyrosinase activity, reduce inflammation, stimulate ceramide synthesis, and strengthen the skin barrier, resulting in less pigmentation and improved skin resilience.
• Tripeptide-5 — boosts collagen synthesis alongside Vitamin C, visibly improving skin firmness and smoothing wrinkles.
• Multi-Molecular Hyaluronic Acid Complex + Squalane — deeply hydrate multiple skin layers and create a hydro-lipid film that prevents moisture loss, leaving skin plump, elastic, and comfortable.
• Vitamin E — potentiates Vitamin C activity up to 4×, protects against photoaging, and supports a healthy, radiant complexion.

Apply morning and evening to the face, under the eyes, neck and décolleté. For best results, then use the Xceptional Flawless Cream or the C-Illuminating 3D Moisturizer.

The formula contains 15% Vitamin C THD, a highly stable, oil-soluble and highly potent form of Vitamin C, and 3% Niacinamide to reduce wrinkles and sagging skin. Thanks to the reduction in melanin production, the skin immediately brightens by reducing dark areas and discolorations. The serum restores the effects of UV exposure, has anti-inflammatory effects on acne and improves enlarged pores, gray skin and skin texture.

A multi-molecular HA complex is added to form a three-dimensional network for a very deep, moisturizing effect and replenishment of specific skin layers. Squalane, a substance similar to the body's own substance, forms a hydrolipidic film that hydrates, softens and prevents moisture loss while building elasticity and resilience. Bark extract and oleic acid reduce excessive sebum production, reduce enlarged pores and shiny skin and contribute to a smooth, even appearance. Tripeptide-5 strengthens the effect by stimulating collagen production. Fine lines and wrinkles are visibly reduced, firmness and elasticity are improved, pores are reduced in size and visible signs of aging are combated. Vitamin E has an anti-inflammatory effect and fights signs of premature aging, protects against environmental damage and regenerates. For a radiant, youthful complexion with radiance
